I have a database in data center, which is running MySQL, and I want to change the database from data center to host in my company. At that time, I don't want to stop the data base in the data center, is there anyway to this kind of integeration? Thank you...
Replicating:
You can setup a MySQL replicate database at your host. It will start replicating the data from the "old" database server into your new one asynchronously while the application is running.
(source: mysql.com)
Swapping: Afterwards you can switch the application to write to the new database.
(source: mysql.com)
Swapping a master MySQL with a slave MySQL replicate: http://dev.mysql.com/doc/refman/5.1/en/replication-solutions-switch.html
MySQL Replication: http://dev.mysql.com/doc/refman/5.1/en/replication.html
You could setup the new Mysql server as replication slav and then switch the connection in your application from the old to the new server.

Please I need help, I have an application running well on the Internet but the Network go down drastically sometimes,
So I imported the online database to my offline version. I want to be running the offline version and update the live version on regular basis either automatically with php code or through phpmyadmin. Please anyone with an idea of how I can do that should please help.
Thanks
You can update the local database automatically when the live server gets a chance.
This concept calls database replication(Master Slave Model).
You can slave your local database which doesn't need static IP. You can set it anywhere.
Master Database need must need static IP. And you can connect as many slaves as you want with the master database.
The Master database automatically sent changes to all slaves.
My MySQL database (local server) is connected to a weather station. The data are updated continuously on my local server. My idea is to develop a web application that allows me to access this data.
My local database (MySQL) has to be replicated on a remote server (phpmyadmin)
The architecture is as follows:
My questions are:
1- How I do the connection ? I know that I can import my cvs file manually but I don't want to do this.
2- Can I update the datas automatically in my remote server ?
NOTE: I only want to queries on my remote server (phpmyadmin), I will not create or modify new datas.
Thanks you for your help.
As i understood, you want to make a copy of your local mysql data on a remote server.
first of all phpmyadmin is a tool or webapp to access mysql , it is not a server itself.
and second
there are two type of replication approach
Master-slave (read from slave , write to master, that will sync to slave)
How to do it
Master- Master (whatever operation are on master that will also replicate on other master) How to do it (Master-Master replication is deprecated. See Group Replication as a replacement)
You can choose the approach as per your requirement
Master-master vs master-slave database architecture?

I am using Mysql, I have two DB in two different system. I want my local DB to be synced with remote DB. both the Schema will be having same table and column.
whenever a change occurs in remote DB that change / Update should happen in my Local DB.
How to do it???
Thanks in Advance.
What you'd need is a replication setup using a multi-source setup as described in the MySQL Documentation.
I have two databases. One is on local server and the other is on a production server. I'm continuously working on the local server and after approval I want to update production server. Wih the current setup, I need to take dump or copy or export of database and then import into production database, every time. Is there any way of synchronization method in phpmyadmin for database on different server.
It is possible to synchronize a model in MySQL Workbench with a live database?
Other then this, how can I do this? I'm able to use queries, the command line and phpmyadmin itself.
Please specified any simple method.
The "synchronisation" feature you are looking for is called replication. A replication can be set up between a master and a slave machine. It does not rely on a constant connection, but stores all changes on the master and replays all those changes on the slave once a connection is established.
I'm using MySql Workbench and WAMP Server. I have a database on the server and when I click reverse engineering on the workbench it imports the db structure, but not any of the inserts. What do I do to get the db data as well as the structure into the workbench.
Also on a separate point as I was using workbench, i noticed it did not automatically sync with the db on the server, ie. when i insert a new row, it did not reflect in the server.. must I forward engineer the db to the server every time i make a change? So sorry for my lack of understanding
MySql Workbench reverse engineering is only to obtain the Schema of the database.
If you want to search the database, make backups, obtain the schema and much more then you can use phpMyAdmin. There are some installers which configures the whole system to work with WAMP enviromment and includes it, like Xampp or ZendServer;
